CLAMP.

Specification of Letters Patent.

Application led May 13, 1913.

Patented (let. 6, 1914. serial No. 767,390.

To all whom t may concern Be itknown that I, RALPH C. FRAZEE, a citizen of the United States, residing at East Hampton, in the county of Suifolk and State of New York, have invented certain new and useful Improvements in Clamps, of which the following is a specification.

My present invention relates to clamps whereby two conduits may be joined for the purpose of conveying iluid and relates more particularly to that class 0f clamps which are adjustable.

The principal object of my invention is to provide a clamp of the character described which is susceptible of use for joining two conduits having different external diameters, suoli as the connection of a radiator in an automobile, with the jaclecting of the engine.

-i further object of my invention is to provide an adjustable clamp so that it may be made to conform to substantially the external surface of one of the conduits at the joint. By providing a clamp of this character, and more particularly for use as hereinbefore mentioned, it is not necessary for a repair man to carry in stock a number of clamps, according to the designs of radiators now in common use, but one type of clamp will serve for practically any radiator.

Another object of my invention is to pro vide retaining portions on one of the parts of a two part clamp so disposed that they will in no way injure the conduits held by the clamp and will enable the parts to be drawn tightly together for the purpose of providing a substantially luidtight joint between the conduits.

Other objects of the invention will appear in the following detail description taken in connection with the accompanying drawings forming a part of the speciiication, and in which drawing:

Figure l is a front elevation of a clamp constructed according to my invention; Fig. 2 is a central vertical section through the same; Fig. 3 is an end elevation ofv the clamp; and F ig. 4 is a top plan view ofthe same.

In the drawings, where similar characters refer to similar parts, 5 designates an arcuate clamp member in the form of a band and il, a coacting spiral shaped clamp member in band. The latter, in use, is adapted to lie within the internal periphery of the arcuate clamp member and' is resilient so that its diameter may be increased or diminished as desired.v

The clamp member 5 has a plurality of4 two members are assembled in operative po,

sition to each other. This clamp member 6 also carries an oil'set portion 1l, similar to portion 8, also accommodating a portion of the retaining member 9.

vWhile I have shown the bolt 9, together with a nut 12 for holding the clamp members one rigid with the other, -any other suitable device may be substituted therefor without departing from the spirit or scope of my invention.

It is to be noted that, inasmuch as the member 6 is spiral in shape, it includes a metallic spanning portion 13 adjacent the offset portions 8 and ll so that if the outer conduit joined, is of a yieldable character, it will not interfere with the tightening of the clamp members inoorder that they may serve their purpose to provide a substantially fluid tight joint. Furthermore, the clamp members may be struck from a sheet of metal and bent to coact as hereinbefore described. The tangential struck portions l0 provide a wedge-shaped recess for hat portion of the clamp member 5 intermediate the apertures 7 and enable the clamp members to be brought tightly in engagementA with each other so as to bend one conduit over another.

ln practice, the clamp member 6 is first disposed about the conduit and turned upon itself so as so tightly embrace the conduit. The second clamp member 5 is then disposed with its apertures receiving certain of the outwardly struck portions 10, according to the diameter of the conduit, and the bolt 9 is then passed through the apertures in offset portions 8 and 13 and the nut l2 turned tight. This provides a clamp which will ref tain the conduits in substantially fluid tight engagement and is well adapted for use in connection with the conduits joining a radiator with the packeting of an engine used on automobiles, and which are subjected to much vibration.

veiitimzm A clamp 'for genemicircular objects coin- 'prising a clamping strip of metal having one active with said lugs upon said first named st11p and having its end remote from said openings bent to form a clamping lug and disposed abreast of said rst named olamp- 1E ing lug and on said underla ped portion. In testimony whereof I a X my signature 1n presence of two Witnesses.
